$(BUGSTITLE Compiler Changes,
$(LI $(LNAME2 iteration_closure, `opApply` now conservatively allocates a closure unless marked `scope`)

$(P This breaking change was required to fix bug with `@safe` violation: $(BUGZILLA 16193).)

$(P To list all places where closure may be allocated after the change, use `-transition=safe`
compiler switch.)

$(P Example:)

---
struct S1 {
int opApply(int delegate(int) dg);
}

struct S2 {
int opApply(scope int delegate(int) dg);
}

void foo() {
foreach(i; S1.init) { // will allocate closure
}
foreach(i; S2.init) { // won't allocate closure
}
}

$(P Enables enhanced `@safe` checking, which will break some existing code.)
$(UL
$(LI Prevents dereferencing `array.ptr` because that bypasses array bounds check.)
$(LI Assumes opApply delegate parameter escapes unless marked `scope`. Escaping
delegates often require a GC allocated closure.)
